BIG BEAR LAKE, Calif. 
Authorities say camping gear was found along with weapons inside the burned-out truck belonging to Christopher Dorner, the former Los Angeles police officer suspected in three killings who is the subject of a manhunt in Southern California's snow-covered mountains.

Los Angeles police Sgt. Rudy Lopez said Sunday that the truck was so charred that investigators couldn't be more specific about the nature of its contents.

SWAT teams with air support and bloodhounds fanned out for the fourth day to search for Dorner, who has vowed revenge against several former LAPD colleagues whom he blames for ending his career.

Authorities planned a 1 p.m. news conference to announce a reward for information leading to the arrest of 33-year-old fugitive.

Chief Charlie Beck has ordered a review of the 2007 disciplinary case that led to Dorner's dismissal.

SWAT teams with air support and bloodhounds fanned out again Sunday in snow-covered mountains, searching for a former Los Angeles police officer suspected in three killings.

Authorities planned a 1 p.m. news conference in downtown Los Angeles to announce a reward for information leading to the arrest of Christopher Dorner, who has vowed revenge against several former LAPD colleagues whom he blames for ending his career.

On Saturday, Chief Charlie Beck said officials would re-examine the allegations by Dorner, 33, that his law enforcement career was undone by racist colleagues. While he promised to hear out Dorner if he surrenders, Beck stressed that he was ordering a review of his 2007 case because he takes the allegation of racism in his department seriously.

"I do this not to appease a murderer. I do it to reassure the public that their police department is transparent and fair in all the things we do," the chief said in a statement.

Authorities suspect Dorner in a series of attacks in Southern California over the past week that left three people dead. Authorities say he has vowed revenge against several former LAPD colleagues whom he blames for ending his career. The killings and threats that Dorner allegedly made in an online rant have led police to provide protection to 50 families, Beck said.

A captain who was named a target in the manifesto posted on Facebook told the Orange County Register he has not stepped outside his house since he learned of the threat.

"From what I've seen of (Dorner's) actions, he feels he can make allegations for injustice and justify killing people and that's not reasonable," said Capt. Phil Tingirides, who chaired a board that stripped Dorner of his badge. "The end never justifies the means."

On Saturday, the scaled-back search party took advantage of a break from stormy weather to look for Dorner in the San Bernardino mountains, about 80 miles northeast of downtown Los Angeles, where his burned-out pickup truck was discovered Thursday. Officers went door-to-door to some 600 cabins in the ski resort area.

A law enforcement officer told The Associated Press authorities found weapons in the truck. The officer spoke on condition of anonymity because the probe is ongoing.
